About Peggy

Hello! As your personal dietitian, my goal is to make nutrition feel less complicated and more like a lifestyle. I have over 25 years of nutrition experience and have counseled thousands of patients to-date, providing personalized nutrition recommendations in a relaxed and comfortable style. I have spent a large portion of my career in the ob/gyne space but have also worked with many male clients, as our office employs a functional medicine doctor that treats both men and women. ​ ​

Approach to care

I'm also a Certified LEAP therapist, which means I specialize in food sensitivity testing. I utilize a patented blood test called MRT (Mediator Release Testing) to identify your unique set of foods that contribute to symptoms of IBS, GERD, migraines, joint/muscle pain, eczema/psoriasis, chronic sinusitis, and other inflammatory or autoimmune conditions. Based on your blood results, we'll create a personalized elimination diet to help reduce your symptoms by as much as 50% in 2 weeks. We'll check your progress via symptom surveys in order to best expand your diet. I can also order and interpret GI Map tests, a stool test which provides a comprehensive overview of your microbiome. This will help us detect what is upsetting your microbial balance and will give us a snapshot of your digestion, absorption, inflammation, and immune health. Together we'll collaborate on a care plan, which will include carefully curated supplements and dietary guidelines based on your stool test results.

Your first session with Peggy

My goal is to listen to your dietary needs and truly tailor an approach that best fits your nutrition goals. I strongly believe, and can fully explain, why there is no such thing as one diet that fits all. I believe in "test don't guess," and my best tools to employ include LEAP-MRT Food Sensitivity Testing as well as GI Map Stool Testing. I can also review and help you to curate your supplement routine.

Education

I hold a Master's degree in Public Health from the University of Illinois at Chicago, graduating magna cum laude, and I double majored in biology and psychology as an undergrad at Loyola University, graduating cum laude.

Hobbies

I am married and the mother of 2 young adults. I love spending time with friends, warm weather, outdoor walks, traveling, and getting to a beach as often as possible!
